| * drm/vc4: Fix the "no scaling" case on multi-planar YUV formatsBoris Brezillon2018-09-101-13/+12Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there's no scaling requested ->is_unity should be true no matter the format. Also, when no scaling is requested and we have a multi-planar YUV format, we should leave ->y_scaling[0] to VC4_SCALING_NONE and only set ->x_scaling[0] to VC4_SCALING_PPF. Doing this fixes an hardly visible artifact (seen when using modetest and a rather big overlay plane in YUV420). Fixes: fc04023fafec ("drm/vc4: Add support for YUV planes.")

* | drm: extract drm_atomic_uapi.cDaniel Vetter2018-09-091-0/+1

This seems to almost perfectly split the rather big drm_atomic.c file into 2 equal sizes. Also adjust the kerneldoc and type a very terse overview text. v2: Rebase. v3: Fix tiny typo. v4: - Fixup armada, newly converted atomic driver hooray! - Fixup msm/dpu1, newly added too.

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | A new helper function(__drm_atomic_helper_plane_reset) has been added for linking a plane with its state and resetting the core properties(alpha, rotation, etc.) to their default values. Use that instead of duplicating the logic. __drm_atomic_helper_plane_reset initializes the alpha property to its max value, which is defined by the drm core as DRM_BLEND_ALPHA_OPAQUE, so nothing changes regarding the alpha value.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commits: 34a2ab5e0689 ("drm: Add acquire ctx parameter to ->update_plane") 1931529448bc ("drm: Add acquire ctx parameter to ->plane_disable") a pointer to a drm_modeset_acquire_ctx structure was added as an argument to the method prototypes. The transitional helpers are supposed to be directly plugged in as implementations of these methods, but doing so generates a warning. Add the missing argument. A number of buggy users were added for drm_plane_helper_disable() which need to be fixed up for this change, which we do by passing a NULL ctx argument.

By displaying SAND buffers directly, we can avoid needing to use the ISP to rewrite the SAND H.264 output to linear before display. This is a joint effort by Dave Stevenson (who wrote the initial patch and DRM demo) and Eric Anholt (drm_fourcc.h generalization, safety checks, RGBA support). v2: Make the parameter macro give all of the middle 48 bits (suggested by Daniels). Fix fourcc_mod_broadcom_mod()'s bits/shift being swapped. Mark NV12/21 as supported, not YUV420.

| * | drm/vc4: plane: Expand the lower bits by repeating the higher bitsMaxime Ripard2018-05-171-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The vc4 HVS uses an internal RGB888 representation of the frames, and will by default expand formats using a lower depth using zeros. This causes an issue when we try to use other compositing software such as pixman that fill the missing bits by repeating the higher significant bits. As such, we can't check the display output in a reliable way by doing a software composition and an hardware one and compare both. To prevent this, force the same behaviour so that we can do such things.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc().

Note that the in-kernel BO cache is always purged before the purgeable cache because those objects are known to be unused while objects marked as purgeable by a userspace application/library might have to be restored when they are marked back as unpurgeable, which can be expensive.

* drm/vc4: Add T-format scanout support.Eric Anholt2017-06-161-4/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The T tiling format is what V3D uses for textures, with no raster support at all until later revisions of the hardware (and always at a large 3D performance penalty). If we can't scan out V3D's format, then we often need to do a relayout at some stage of the pipeline, either right before texturing from the scanout buffer (common in X11 without a compositor) or between a tiled screen buffer right before scanout (an option I've considered in trying to resolve this inconsistency, but which means needing to use the dirty fb ioctl and having some update policy). T-format scanout lets us avoid either of those shadow copies, for a massive, obvious performance improvement to X11 window dragging without a compositor. Unfortunately, enabling a compositor to work around the discrepancy has turned out to be too costly in memory consumption for the Raspbian distribution. Because the HVS operates a scanline at a time, compositing from T does increase the memory bandwidth cost of scanout. On my 1920x1080@32bpp display on a RPi3, we go from about 15% of system memory bandwidth with linear to about 20% with tiled. However, for X11 this still ends up being a huge performance win in active usage. This patch doesn't yet handle src_x/src_y offsetting within the tiled buffer. However, we fail to do so for untiled buffers already.

| | | | | | | | | | | | | | | | | | | | DRM_FORMAT_XBGR8888 and DRM_FORMAT_ABGR8888 are 2 of the native formats used in Android, so enable them for VC4. There seems to be no logic behind HVS_PIXEL_ORDER_xxxx naming, but HVS_PIXEL_ORDER_ARGB seems to work correctly.

* | drm/atomic: Add drm_atomic_crtc_state_for_each_plane_stateDaniel Vetter2016-06-021-2/+3
|/ | | | | | | | | | | | | | | | | | | | | | ... and use it in msm&vc4. Again just want to encapsulate drm_atomic_state internals a bit. The const threading is a bit awkward in vc4 since C sucks, but I still think it's worth to enforce this. Eventually I want to make all the obj->state pointers const too, but that's a lot more work ... v2: Provide safe macro to wrap up the unsafe helper better, suggested by Maarten. v3: Fixup subject (Maarten) and spelling fixes (Eric Engestrom).

* drm/vc4: Add support for YUV planes.Eric Anholt2016-02-161-58/+198
| | | | | | | | | | | | This supports 420 and 422 subsampling with 2 or 3 planes, tested with modetest. It doesn't set up chroma subsampling position (which it appears KMS doesn't deal with yet). The LBM memory is overallocated in many cases, but apparently the docs aren't quite correct and I'll probably need to look at the hardware source to really figure it out.
